Whomp. Whomp. Whooooomp. Without a motion sensor, this light is pointless. The On and Off functions work. The light changes color and brightness. Every other feature seems okay except for the motion sensor. We tried every combination of button pressing, hand motion, and waiting around for the light to go out (after it's pressed On) when it has no motion to sense. All the light will do is turn On and Off manually. Neither sensor mode operates. It's very disappointing. Where we planned to use the light requires the motion sensor. It's not practical to have to use the remote to turn the light on and off each time. So unfortunately, this item is a waste. We wanted to like it. It is thin and compact (like a Frisbee light). The magnet mounting seemed handy. The remote is a feather, and it's straightforward to operate. The brightness is average. Before we realized the sensor wasn't working, we tried it out in the spot we intended, and truthfully, it didn't light up the space as we expected. It would do, but this light would really be best in very small areas. All in all, the idea of small, wireless motion light is good in theory, and we hoped it to be useful. But after receiving a unit with a broken motion sensor, we can't honestly give this particular product anything more than a low rating.
